A Pilot Study to Assess the Safety of Oral Insulin in Patients With Nonalcolholic Steatohepatitis (NASH)

Phase 2

Completed

Conditions: Non-Alcoholic Steatohepatitis (NASH)
Type2 Diabetes Mellitus

Interventions: Biological: Oral Insulin

Registration Number: NCT02653300

Lead Sponsor: Oramed, Ltd.

Brief Summary: This is an open, pilot study using the oral ORMD-0801 insulin formulation in patients with NASH and confirmed type 2 DM or pre-diabetes. The study will consist of a Screening, placebo run-in, treatment phase and end-of-study phase.

Detailed Description: This exploratory study will first enroll 10 patients with NASH and type 2 DM, to evaluate the safety of oral insulin and to measure the change in liver fat content.

At the completion of their 4-week follow-up period, results will be presented to the Helsinki Committee. Following approval, an additional 20 patients will be enrolled. The size of the study population was determined by the investigator (with literature review) to be sufficient to show trends of reducing liver fat content by analysis of MRI PDFF (MRI-Proton Density Fat Fraction) images, the FibroMax™ Test and Fibroscan® including Controlled Attenuation Parameter (CAP™). CAP™ is a measure of the ultrasound attenuation to quantify steatosis in the liver.

Recruitment & Eligibility

Status: COMPLETED

Sex: All

Target Recruitment: 10

Inclusion Criteria

Known type 2 DM according to American Diabetic Association (one of the three needed): Fasting Plasma Glucose ≥126 mg/dl or 2h postprandial (PG) following 75g OGTT ≥ 200 mg/dl or HbA1C > 5.7% or on treatment with metformin
Abdominal ultrasound (US) proven fatty liver performed within 6 months before randomization, confirmed by central US.
Fat concentration in the liver of S2 (moderate steatosis, 6-32% hepatocytes with steatosis) or more as measured by Fibromax.
Signature of the written informed consent.
Negative pregnancy test at study entry for females of child bearing potential.
Females must have a negative urine pregnancy test result at screening, prior to the start of the run-in period, and at initiation of active dosing. A negative urine and serum pregnancy test must be obtained prior to active dosing. Males and females of childbearing potential must use two methods of contraception.
Females of non-childbearing potential are defined as postmenopausal who a) had more than 24 months since last menstrual cycle with menopausal levels of FSH, b) who are surgically menopausal.
For hypertensive patients, hypertension must be controlled by stable dose of anti-hypertensive medication for at least 2 months prior to screening with BP < 150/<95 mmHg
Patients previously treated with vitamin E (>400IU/day).
Glycaemia must be controlled (Glycosylated Hemoglobin A1C ≤9%) while any HbA1C increment should not exceed 1% during 6 months prior to enrolment).

Primary Outcome Measures

Name	Time	Method
Change in MRI-Proton Density Fat Fraction (MRI-PDFF)	Two timepoints: Baseline (week 0) and Week 12	Absolute Change in MRI-Proton Density Fat Fraction (expressed as percent fat in the liver) from baseline to week 12

Secondary Outcome Measures

Name	Time	Method
Mean Transient Elastography Measurement (Fibroscan)	Two timepoints: Baseline (week 0) and Week 12	Mean Transient elasticity, measured in kPA (kilo Pascal),
Mean Fibrosis Score CAP™ (FibroMax)	Two timepoints: Baseline (week 0) and Week 12	Mean fibrosis score (severity scale of liver fibrosis) measured at baseline and week 12. Fibrosis Score CAP measures the amount of steatosis (fatty change) in the liver. The CAP score is measured in decibels per meter (dB/m). It ranges from 100 to 400 dB/m with higher values indicating more fatty change
